[An analysis of YPLL, WYPLL and VYPLL in Guangzhou, 1983-1994].
In order to assess the health status and risk of various diseases in the population of Guangzhou, the surveillance data of death in 1983-1994 in Guangzhou was analyzed by indicesas: year of potential life lost (YPLL), work year of lost (WYPLL) and valued year of potential life lost (VYPLL). It was indicated that both Chinese standardized mortality rates (CSMR) and Chinese standardized rates (CSYPLLR) had been declined from 448.2 x 10(-5) and 53.16/1000 to 398.6 x 10(-5) and 42.29/1000 during 1983-1994, respectively. It was suggested that the health status of inhabitants in Guangzhou had been gradually improved. Cancer lesion and poisoning, cardiovascular diseases rank top in CSYPLLR, were the most important diseases affecting life span of the inhabitants. Lesion and poisoning, infectious disease, psychotic disease, ranked the first in Chinese tandardized WYPLL rates (CSWYPLLR) and Chinese standardized VYPLL rates (CSVYPLLR), were important factors that periled the society labor force and economic development. By comparison of sex, both CSMR and CSYPLLR were higher in male than in female (u = 14.76, P < 0.01; u = 27.05, P < 0.01, respectively). Although both values of CSWYPLLR and CSVYPLLR were negative, they were still higher in male than in female. The zero-age-group was far more higher than all the other age groups in CSPLLR, CSWYPLLR and CSVYPLLR.
